I used it quite a bit early on during military operations. The ability to see the timing component was key; not only would you plot the purchase locations, but you could play the timeframe of records, work out the timing so you knew the order in which they visited the locations, where they must have stopped for gas along the route. In a classic workflow, you'd then investigate the gas stations, attach them to the event with confidence intervals, pull CCTV footage, see if you can get a payment receipt, and enter all of that data back into palantir. A few days of doing this, and you can build up all a map of every aspect of the drug run; the who what when where and why. It's a fantastic organization system.
I appreciate the technical achievements here. However, I wonder how long before it’s standard practice to track all peoples movement, not just those suspected of a crime. I know of at least one YouTube channel that is always recording all traffic camera streams in Washington so there must be some State entities doing the same. Back in 2020 there was a twitch channel that would play a 9x9 grid of all the livestream footage from the George Floyd protests. I’m sure an archive of that exists somewhere on a LE server.
